So in a fit of nostalgia this weekend I went on steam, bought Chaos Theory and installed it. I'm using Windows 7 64-bit and it works fine, except for one odd quirk. I can't enjoy the game for more than thirty minutes without putting a cool-pack underneath my laptop because once it starts to heat up my whole system crashes. It actually doesn't get too unreasonably hot by the time this happens. I've played more demanding games like Shogun 2 on this laptop and allowed it to get to higher temperatures without anything like this happening before. It seems to only happen when I play Chaos Theory.
What I want to ask is if anybody else has experienced this and if a simple, internal fix is available.
